The Lowdown
Alright, let’s get into it. The forecast is a real slow burn around here, with a long stretch of nothing much before a potential pulse of swell late in the month. Don’t get your hopes up too early.
Karramarro is a point break, and it’s an advanced wave that’s inconsistent, so it takes a bit of a surf to get it going. We’re looking at a pretty quiet start. From Monday the 20th right through to the end of the month, the surf is mostly small, weak, and messy. The combined energy stays under 100 (in the double digits) for most of that time, which is weak. The waves are tiny, the period is short, and the wind is often cross or onshore, making it a bit of a scratchy session. There’s a brief window on Tuesday morning the 21st with a little 4ft swell from the north, but it’s only a 1 out of 10 and the description says “very ordinary.” Not one to paddle out for.
The water temperature is around average for the time of year, nothing unusual there.
Now, the only real standout in this whole 16-day window arrives on Wednesday the 29th of July. The morning session looks promising. We’ve got a 6ft swell from the north-northwest, with a period of 8 seconds, and the wind is glassy, so it’ll be clean. The combined energy jumps right up to 684 (moderate wave energy). For an inconsistent point break, that’s a big number. The conditions are described as “expect very good surf conditions,” and it’s scoring a 3. That’s our best shot. The swell direction is from the NNW, which is a bit off the optimum NW, but with that glassy morning and the size, it’s the only day that looks like it’s really firing. Be aware that this spot can get crowded, so you’ll have company.
After that, the swell drops back down quickly. The Thursday morning the 30th still has a little 6ft swell left, but the wind is onshore, and the quality drops. By the end of the week and into August, it’s back to tiny, weak surf.
So, the takeaway is this: there’s a massive gap from now until the 29th, with almost nothing worth a paddle. If you can wait, the morning of the 29th is your day. The long-range nature of that call means it’s a bit of a gamble, but if the forecast holds, that’s the one.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
